Colin Furze is building the biggest fart machine ever — a valveless engine that will be housed in a specially constructed pair of buttocks. His ultimate goal is to place it on top of the cliffs of Dover and aim it across the Channel towards France.

If all goes well — and why wouldn't it — the contraption will be ready to go on July 24th, between 6:00 and 7:00 pm. His hope is that the French, located 21 miles away, will hear the blast.

"There are reports that in the war people could hear artillery fire from northern France," he writes at his YouTube page, "but will the French hear this."

The machine is a giant valveless jet engine, similar to the one used by the Nazis to power their V-1 bombs during the Second World War. Furze 's configuration creates a plume of fire to accompany its fart-like, deafening roar.
